Fitment and maintenance

Match the sprocket family and mounting pattern to the motorcycle model and year. Confirm chain size, tooth count and clearance before ordering. A change in tooth count changes the final-drive gearing and can affect the chain length and adjustment required.

Inspect the drive chain and both sprockets together; worn components can shorten the service life of replacement parts. Install to the motorcycle manufacturer's assembly and torque specifications, then check chain adjustment and lubrication.
